My ES has a Lexus Premium sound system contains 10 speakers, and you know what ? there are just 8 position in car. What the count 10 speakers is the count 2 positons in dash are coherence speaker as 2 speakers. The other just simple speaker. These speakers in general produce the sound quality is bad and general lacks of treble sound (high frequency).
The solution is: I add a original ML tweeter into the present Pioneer speaker, change the simple speaker with the Pioneer one and amazing, the sound is very very wonderful. It can be compared to the ML sound. You guy can consider !



add ML tweeter into present Pioneer speaker
